Parametric study of the main parameters influencing the catalytic efficiency of a diesel oxidation catalyst: Parameters influencing the efficiency of a diesel catalyst

This work studies the impact of five parameters: CO and HC engine-out emissions, space velocity, average value and profile of exhaust temperature, on Diesel CO and HC tail-pipe emissions. The first part of this work is conducted on a reactor and shows that both HC and CO light-off temperature increases with CO and HC input concentration. CO and HC initial concentration influence the adsorption/desorption capacities of HC only at high temperatures. Space velocity also influences CO and HC conversion efficiency. The second part of this work studies the impact of different combinations of HC and CO engine-out emissions on CO and HC conversion and tail-pipe emissions in the case of New European Driving Cycle. This part proposes that a Diesel oxidation catalyst must be mainly studied at the Urban Part of NEDC, as the CO and HC conversions are very high at the extra-urban part of NEDC. CO and HC conversion efficiencies are also dependent on exhaust temperature and catalytic volume. In the case of two different profiles of exhaust temperature with the same average temperature, CO and HC conversion efficiency is lower in the case of the smoother profile.

Port-city exhaust emission model: An application to cruise and ferry operations in Las Palmas Port

Exhaust emissions cause air pollution and climate change. The exhausts of shipboard fuel combustion are equally damaging particularly, so close to the environmentally sensitive mainland and island coasts, as well as at ports due to their urbanized character. This paper estimates, for the first time, exhaust pollutants related to cruise and ferry operations in Las Palmas Port and, in an island context. Emission assessment is based on a full bottom-up model and messages transmitted by the Automatic Identification System during 2011. Results are described as a breakdown of NOx, SOx, PM_2.5, CO and CO₂, according to ship classes, operative type and time, providing valuable information to environmental policy makers in port-city areas and islands under similar conditions. It is generally concluded that vessel traffic and passenger shipping in particular are a source of air pollution in Las Palmas Port. Emission maps confirm location of hot spots in quays assigned for cruise and ferry operations. Policy recommendations encourage regular monitoring of exhaust emissions and market-based incentives supported by details on polluting and operative profiles. On the other hand, feasibility studies are suggested for automated mooring, LNG bunkering facilities and also shore-side energy services, prioritizing berthing of shipping sectors (or sub-sectors) with the highest share of exhaust emissions once their local effects have been confirmed by a dispersion, exposure and impact assessment.
